20251204 23565600 1.0 TRUE Calculate average slope for the selected parcel. This tool is intended primarily for use as part of a geoprocessing service. CALCULATION OF AVERAGE SLOPE A. Minimum contour interval is 5 feet when the average slope exceeds 10 %; 2 feet when the average slope is less than 10%. B. Measure the total length of contours within the net area of the lot. The net area is the gross area less the vehicle access easements or rights of way. (Exception: when an access easement is exclusively for emergency access, it is not deducted from the gross lot area.) C. Calculate the average slope of the lot using the following formula: S = (0.0023) (I) (L) /An Where: I = contour interval in feet L = total contour length of lot in feet (within net area); multiply total length in inches by map scale An = net area of lot in acres S = average lot slope in percent Calculate S to the nearest 0.1 % Average slope SCCGOV Contour Calculate average slope for the selected parcel.
